When they tracked Maul and Opress to the Scourge gang's base in the caves, Jun-Fan and the clonesoldiers began to combat several wampas that Maul released. The other Jedi, meanwhile, attempted to capture Maul and Opress, who ultimately managed to escape with a hostage after killing Grohto and maiming Tatsu. Jun-Fan used his psychometric abilities on a piece of jewelry that the Sith's hostage had dropped, gathering that they were headed to the planet Pleem's Nexus. Jun-Fan, Koon, and Solok left Tatsu and Kenobi behind due to their injuries and followed Maul and Opress to Pleem's Nexus. They confronted the brothers at a castle as the Sith were attempting to load some treasure—which they planned to use to establish a criminal empire—on their starship.[2]

Jun-Fan chokes Darth Maul.

During the ensuing duel, Jun-Fan and Solok tried to convince Maul to reveal his former Master's identity. Maul used the Force to throw his lightsaber at Jun-Fan, who dodged the attack, although the lightsaberimpaled Solok and killed him. Jun-Fan proceeded to use his unarmed abilities to try and overpower Maul, and eventually began to choke the Sith Lord, determined to end what he considered Maul's evil actions. However, Maul repositioned his right cybernetic leg and kicked Jun-Fan in the abdomen, mortally wounding the Jedi Master. After Maul and Opress escaped when Kenobi and Jedi KnightAnakin Skywalker arrived in their starfighters, Jun-Fan died in Koon's arms.[2]

"I feel the Force around me… taking me… This is one mystery I will explore first, Master."

―Jun-Fan, to Plo Koon, as he succumbs to the injuries dealt to him by Darth Maul[src]

Bruu Jun-Fan was light-skinned with brownhair and eyes, and kept himself in good physical condition. When practicing combat, he was bare-chested and wore brown slacks, and used a lightsaber with a green crystal. He was interested in what happened to an individual upon their demise, believing it to be a mystery. Jun-Fan was dedicated to capturing Darth Maul and Savage Opress, and during his confrontation with Maul on Pleem's Nexus, he attempted to try and convince Maul to reveal his former Sith Master's identity. However, after Maul's lightsaber killed Ko Solok, Jun-Fan abandoned that mentality and was determined to end Maul's life. After Maul mortally wounded Jun-Fan, he remarked that he felt the Force taking him while he was dying.[2]

Jun-Fan's was noted for achieving the rank of Master at a young age, and his skills in unarmed combat were regarded by Grand MasterYoda as being without equal. Jun-Fan was able to defeat B1 battle droids, and he also defeated wampas with blows to their throats and heads. He had good reflexes, being able to dodge Maul's lightsaber when the Sith Lord threw it at him, and was able to overpower Maul in a physical grapple. In addition to his martial arts prowess, Jun-Fan was also skilled in psychometry.[2]
